    A man fires a bullet of mass 200 g at a speed of 5 m/s. The gun is of one kg mass. by what velocity the gun rebounds backwards       [CBSE PMT 1996; JIPMER 2000]            

    A)                         0.1 m/s            

    B)                           10 m/s            

    C)                         1 m/s            

    D)                         0.01 m/s

    Correct Answer: C

    Solution :

                                \[{{v}_{G}}=\frac{{{m}_{B}}{{v}_{B}}}{{{m}_{G}}}=\frac{0.2\times 5}{1}=1\ m/s\]
